PGT Window Installation: The Weston Owner’s Guide
PGT window installation in Weston typically runs $890-$2,400 per opening depending on the series, impact rating, and whether the frame needs structural adaptation for Florida Product Approval compliance. We stock PGT Winguard, WinGuard Vinyl, and EnergyVue series units, and we can usually measure, order, and set replacement windows within 5-10 business days once the survey is complete. Most Weston owners first realize their PGT window is failing when the sash won’t stay open, the lock doesn’t draw the meeting rails tight, or they feel air movement around the frame during a northeast wind event - all signs that the installation, not just the product, has degraded.
Which PGT Models This Applies To
We install across PGT’s residential lines, with the majority of our Weston work falling into three series. Winguard aluminum and vinyl impact windows carry Florida Product Approval numbers starting with FL # and are labeled on the top sash rail or the frame jamb with a stamped metal tag. EnergyVue vinyl non-impact units use a different frame depth, typically 3¼ inches versus Winguard’s 3½ to 4½ inches depending on the DP rating, and the nailing fin configuration changes between the two. WinGuard Vinyl uses a welded-frame construction with integrated lift rails, while aluminum Winguard frames are mechanically fastened at the corners.
The compatibility gotcha we see most often in Weston: owners with 2015-2019 Winguard aluminum single-hungs try to swap in current-production vinyl sashes, and the frame depth mismatch leaves a visible gap at the sill. PGT changed the interlock geometry in 2020. We verify against the original order record or measure the frame pocket directly. For OEM versus aftermarket, we specify PGT factory units for anything impact-rated because the NOA (Notice of Acceptance) traceability is required for permit closeout in Broward County. On non-impact EnergyVue, we will quote a quality equivalent from CWS or ES Windows if the lead time or price works better for the owner, but we document the substitution in writing before ordering.
Signs Your PGT Window Installation Is Failing

- Sash drops or won’t hold position. The balance system, either a coil spring or block-and-tackle depending on the series year, has lost tension. In Weston, we see this accelerate when owners pressure-wash the tracks and force water past the balance cover seals.
- Visible daylight between the sash and frame at the lock side. The installation has settled or the shims have compressed, throwing the frame out of square. The lock hardware is doing the sealing work instead of the weatherstrip, and the weatherstrip itself starts to deform.
- Condensation between the glass panes. The insulating glass unit seal has failed. PGT’s standard IGU warranty is 10 years for residential, but the installation warranty from the original contractor often expired long before. We see this most on west-facing elevations in Weston Hills where thermal cycling is aggressive.
- Frame corrosion at the sill or jamb. Aluminum Winguard frames develop pitting when the weep holes are caulked over during a sloppy repaint, trapping water against the metal. We document this with photos and show the owner exactly where the drainage path was blocked.
- Operation gets stiff seasonally. The frame is expanding against a too-tight installation pocket. PGT specifies clearances by series and DP rating; a Winguard 550 installed to the same rough opening as a standard 375 will bind in July and rattle in January.

| Scope | Typical Range in Weston |
|---|---|
| PGT Winguard aluminum single-hung, standard size, retrofit install | $890-$1,350 |
| PGT Winguard vinyl single-hung, impact-rated, new construction or full-frame replacement | $1,200-$1,850 |
| PGT EnergyVue vinyl double-hung, non-impact, with low-E upgrade | $980-$1,450 |
| PGT sliding glass door, Winguard impact, two-panel | $2,000-$2,800 |
| Structural adaptation for Florida Product Approval compliance (sill pan, fastening pattern, flashing) | $180-$420 additional |
What drives the range: the product line itself, whether we’re doing a pocket retrofit or full-frame removal, the condition of the existing sill and header, and whether the original installation was permitted to the current Broward County amendment cycle. Our quote includes the measured survey you keep, the PGT unit with factory warranty registration, installation labor, perimeter sealant and backer rod, interior trim repair or replacement as needed, and the documented photo record. The 365-Day Done Right Promise covers labor and materials; if the sash doesn’t operate the way it did on day one, we return and correct it. No change orders. The price on the measured survey is the price on the invoice.
DIY or Call Us?

There is no dangerous spring or electrical component in a window installation, but there is a genuine risk of water intrusion liability that can run into five figures before you discover it. An owner can safely check: whether the weep holes are clear, whether the lock draws the sash tight with moderate pressure, and whether caulk is missing at the exterior perimeter. Do not remove the sash or attempt to adjust the frame yourself. PGT’s impact-rated units weigh 40-60 pounds per sash depending on the laminated glass thickness, and the fastening pattern for Miami-Dade and Broward wind zones is specified to the inch in the NOA. Miss the pattern, or use the wrong fastener length, and the installation fails inspection and may void your homeowners policy.
We have re-installed windows that competent DIYers set themselves, and the consistent error is insufficient slope at the sill or fastener placement that misses the structural member. The window looks fine until the first driving rain. Call (754) 812-9260 and we will measure, quote in writing, and install to the Haven Standard with the documentation you need for your records.
FAQs
A properly installed PGT impact window should last 20-30 years in Weston’s climate, though the balance system typically needs attention at 12-15 years and the IGU seal may fail at 10-15 years on high-exposure elevations. The salt-laden air off the Everglades accelerates hardware corrosion compared to inland Broward County, which is why we specify stainless or coated fasteners even when the NOA allows galvanized. Call (754) 812-9260 for an exact quote on your specific series and exposure - estimates are free.
Sometimes. A dropped balance, failed lock, or torn weatherstrip can be repaired or replaced as a component service. But if the frame is out of square, the IGU has failed, or the installation itself is leaking air or water, component repair is throwing good money at a structural problem. We will tell you which category you’re in after the measured survey, and we provide a free second opinion on any written estimate you’ve already received. Call (754) 812-9260.
A standard single-hung replacement takes 2-3 hours per opening once the product is on-site; a full-frame removal with structural adaptation takes 4-6 hours. We do not promise same-day completion because the measured survey and the written quote are the same document, and we will not start work until you have reviewed and retained that document. Most Weston jobs are scheduled within 5-10 business days of quote acceptance. Call (754) 812-9260 to schedule your measured survey.
We stock common PGT hardware and we maintain relationships with the regional distribution network for Winguard, WinGuard Vinyl, and EnergyVue series. Standard sizes and white or bronze frames typically ship within 3-5 business days; custom sizes, interior color laminates, or SDL (simulated divided light) grids extend that to 2-4 weeks. We do not stock full window units in every size because PGT builds to order, and we would rather quote an accurate lead time than sell you what happens to be in a warehouse. Call (754) 812-9260 for current availability on your series and size.
Sonia Raman has been running window and door installations across Broward County since she picked up her first glazing tools in the shop programs at Miami Dade College, and she still checks every frame from three reference points before calling it square. The salt-laden air off the Everglades, especially on homes backing the Weston Town Center corridor, has taught her that a bad seal always reveals itself eventually. Measure it right the first time. The window does not care how confident you were.
Call (754) 812-9260 to schedule your free measured survey and written estimate. We also install and service CGI, CWS, and ES Windows product lines, specified by what your opening requires, not by what is in stock.
